Product Details

Niobium Rod & Niobium Bar Standard

All niobium and niobium alloys rod & bar products follow standard ASTM B392, such as pure niobium rod & bar (R04200 , R04210) , Nb1Zr (R04251 R04261) , Nb10Zr , C103, Cb752, C129Y, FS85, Nb50Ti rod & bar and so on.

Niobium Rod & Niobium Bar Introduction

  • Niobium and niobium alloy rod & bar are widely used in chemistry, electronics, aerospace and other fields due to its advantages of high melting point, corrosion resistance and cold processing.

  • Appearance quality: cold and annealed rods are free of cracks, folds, holes, metal and non-metallic inclusions, cold-lap, residual lubricant, oxides and other smudges on the surface while hot treatment rods are free of cracks, folds and double-skin.

  • We produce pure niobium rod & bar and other niobium alloys rod & bar such as C-103 , Cb-752 , C129Y , Nb50Ti rod & bar.
